Cargo check gives error where cargo build does not

[ghost]

cargo check gives the following error in my code:

error[E0277]: the trait bound `rubato_server::db::DbConnection: rocket::request::FromRequest<'_, '_>` is not satisfied

cargo run and cargo build do not give this error (and run/compile correctly).

You can find the code (as minimal as I could get it) here

I ran this locally with Cargo build from master and I think this was fixed with #3426, so this should get fixed as soon as the next nightly is released!

In any case, though, thanks for the report!
